CI上带有“Parse error”的PHPunit测试错误

我正在使用的帮助下对代码进行单元测试 phpunit 9.3.8 . 测试在我的本地开发环境中运行良好(我运行的是Windows 10, PHP 7.4.2 具有 Xdebug 2.9.2 )但由于尝试运行时出现分析错误而失败 phpunit 在Gitlab CI上(CI运行最新的alpine linux映像)。

错误是:

Script phpunit handling the test event returned with error code 2

报告第21行 Reporter.php 档案如下:

<?php namespace utilities\Reporter;

/**
 * The Reporter class is responsible for returning data to the client.
 */
class Reporter
{
    /** This is the code of the answer.
     * (more comments)
     * @var int The status code.
     */
    private int $code; //<-- This is line number 21

第12行 ReporterTest.php

<?php

use PHPUnit\Framework\TestCase;
use utilities\Reporter\Reporter;

class ReporterTest extends TestCase
{
    protected $reporter;

    protected function setUp(): void
    {
        $this->reporter = new Reporter(); // <-- Line 12 is here
    }
}

我正在使用PHPunit的fixtures函数,定义为:

PHPUnit支持共享设置代码。在运行测试方法之前,将调用名为setUp()的模板方法。setUp()用于创建要测试的对象。
